TECHNICAL FIELD

The present document relates to the field of mobile wirelesscommunications, and more particularly, to a modulation processingmethod, a user equipment (UE) and a base station in a wirelesscommunication system.

BACKGROUND

In the mobile communication system, due to the time-varyingcharacteristic of the wireless fading channel, the communication processhas a lot of uncertainties, and on one hand, in order to improve thesystem throughput, a high-order modulation and a low redundancy errorcorrecting code with a relatively high transmission rate are used forthe communication, therefore the system throughput indeed improvessignificantly when the signal to noise ratio of the wireless fadingchannel is relatively ideal, however, when the channel is in deepfading, it cannot guarantee a reliable and stable communication, and onthe other hand, in order to ensure reliability of the communication, alow order modulation and a high redundancy error correcting code withrelatively low transmission rate are used for the communication, thatis, it ensures a reliable and stable communication when the wirelesschannel is in deep fading, however, when the signal to noise ratio ofthe channel is relatively high, due to a relatively low transmissionrate, the increase of system throughput is restricted, thereby resultingin a waste of resources, and in the early development of mobilecommunication technology, people fights the wireless fading channeltime-varying characteristic only by increasing the transmission power ofthe transmitter and using a low-order and large redundancy modulationand coding method to ensure the communication quality of the system whenthe channel is in deep fading, and how to increase the system throughputhas not been considered, and along with improvement in technology, therehas appeared technology which adaptively adjusts its transmission power,modulation and coding scheme and data frame length based on the channelstate to overcome the channel time-varying characteristic, so as toobtain the best communication effect, and the technology is known asadaptive coding and modulation technology, which is the most typicallink adaptation technology.

In the Long Term Evolution (LTE) system, the control signaling whichneeds to be transmitted in the uplink has Acknowledgement/NegativeAcknowledgement (ACK/NACK), and three forms which reflect the channelstate information (CSI) of the downlink physical channel: channelquality indication (CQI), Pre-coding Matrix Indicator (PMI), and RankIndicator (RI).

The CQI is an index used to measure the quality of the downlink channel.In the 36-213 protocols, the CQI is indicated with values of integersfrom 0 to 15, which respectively represent different CQI levels, anddifferent CQIs correspond to respective Modulation and Coding Schemes(MCS), see Table 1. The CQI grade selection should follow the followingguidelines:

TABLE 1 CQI index Modulation Code rate × 1024 Efficiency 0 out of range1 QPSK 78 0.1523 2 QPSK 120 0.2344 3 QPSK 193 0.3770 4 QPSK 308 0.6016 5QPSK 449 0.8770 6 QPSK 602 1.1758 7 16 QAM 378 1.4766 8 16 QAM 4901.9141 9 16 QAM 616 2.4063 10 64 QAM 466 2.7305 11 64 QAM 567 3.3223 1264 QAM 666 3.9023 13 64 QAM 772 4.5234 14 64 QAM 873 5.1152 15 64 QAM948 5.5547

The Quadrature Amplitude Modulation (QAM) in Table 1 represents thequadrature amplitude modulation, and the Quadrature Phase Shift Keying(QPSK) represents the quadrature phase shift keying which is a digitalmodulation scheme.

The selected CQI level should be such that the block error rate of thePhysical Downlink Shared Channel (PDSCH) transport blocks correspondingto the CQI under the corresponding MCS does not exceed 0.1.

Based on one non-limiting detection interval between the frequencydomain and the time domain, the User Equipment (UE) will obtain thehighest CQI value which corresponds to each maximum CQI value reportedin the uplink subframe n, and the CQI index is in the range of 1-15, andmeets the following condition, and if the CQI index 1 does not meet thecondition, the CQI index is 0: the error rate of a single PDSCHtransport block does not exceed 0.1 when being received, the PDSCHtransport block includes joint information: modulation scheme andtransport block size, which corresponds to one CQI index and a group ofoccupied downlink physical resource blocks, that is the CQI referenceresource. Herein, the maximum CQI value is the maximum CQI value whenensuring that the Block Error Ratio (BLER) is not greater than 0.1, andit helps to control the resource allocation. Generally, the smaller theCQI value is, more resources will be occupied, and the BLER performanceis better.

For the joint information corresponding to one CQI index and having thetransport block size and modulation scheme, if: the joint informationtransmitted by the PDSCH in the CQI reference resource according to therelated transport block size can be notified with signaling, inaddition:

the modulation scheme is characterized with the CQI index and uses thejoint information including the transport block size and the modulationscheme in the reference resource, and the effective channel coding rategenerated by the modulation scheme is the most closing effective channelcoding rate which can be characterized with the CQI index. When there ismore than one of the joint information and all of the join informationcan generate similarly closing effective channel encoding ratecharacterized by the CQI index, the joint information having the minimumtransport block size is used.

Each CQI index corresponds to one modulation scheme and transport blocksize, and the corresponding relationship between the transport blocksize and the number of physical resource blocks (NPRB) can be showedwith a table. The coding rate can be calculated according to thetransport block size and the NPRB.

In the LTE system, the ACK/NACK is transmitted on the physical uplinkcontrol channel (PUCCH) in the PUCCH format 1/1a/1b, if the UserEquipment (UE) needs to transmit uplink data, the data are transmittedon the physical uplink shared channel (PUSCH), the CQI/PMI, RI feedbackmay be a periodic or aperiodic feedback, and the specific feedback isshown in Table 2:

TABLE 2 uplink physical channels corresponding to periodic feedback andaperiodic feedback: Periodic CQI Aperiodic CQI Scheduling pattern reportchannel report channel Frequency non-selective PUCCH Frequency selectivePUCCH PUSCH

Herein, for the periodic CQI/PMI, RI feedback, if the UE does not needto transmit the uplink data, the periodic CQI/PMI, RI feedback istransmitted on the PUCCH in PUCCH format 2/2a/2b, if the UE needs totransmit the uplink data, the CQI/PMI, RI is transmitted on the PUSCH;the aperiodic CQI/PMI, RI feedback is only transmitted on the PUSCH.

The Long-Term Evolution (referred to as LTE) Release 8 standard definesthe following three downlink physical control channels: Physical ControlFormat Indicator Channel (referred to as PCFICH), Physical HybridAutomatic Retransmission Request Indicator Channel (referred to asPHICH) and Physical Downlink Control Channel (referred to as PDCCH).Herein the PDCCH is used to carry Downlink Control Information (referredto as DCI), including: uplink, downlink scheduling information, anduplink power control information. The DCI format is divided into thefollowing: DCI format 0, DCI format 1, DCI format 1A, DCI format 1B, DCIformat 1C, DCI format 1D, DCI format 2, DCI format 2A, DCI format 2B,DCI format 2C, DCI format 2D, DCI format 3, and the DCI format 3A, andthe like.

In the LTE, downlink control information such as the coding andmodulation scheme, the resource allocation position and the HARQinformation need to be defined in the downlink control signaling.Herein, the downlink scheduling of the base station determines thecoding and modulation scheme, and especially, the protocol defines amodulation and transport block size table, and each row of the tablecorresponds to one MCS index, for each MCS index, the modulation andtransport block size table defines one combination of modulation schemeand code rate, and the specific table can refer to the LTE 36.213standard, and one MCS index essentially corresponds to one spectralefficiency, the selection for the MCS index needs to refer to thedesired CQI value, generally the base station needs to consider thespectral efficiencies of the two parties in the implementation. The basestation determines the MCS index and also needs to determine theresource allocation information, and the resource allocation providesthe number of physical resource blocks (NPRB) which need to be occupiedin the downlink transmission, the LTE standard also provides a transportblock size (TBS) table, and the table defines the TBS size under thecondition of a given MCS index and the number of physical resourceblocks (NPRB), and with these coding and modulation parameters, thedownlink coding and modulation can be performed.

In Release 10 (R10), the UE is semi-statically configured to receive thePDSCH data transmission through the high-layer signaling based on one ofthe following transmission modes and according to the PDCCH indicationof UE-Specific search space:

Transmission Mode 1: Single-antenna port; port 0

Transmission Mode 2: Transmit diversity

Transmission Mode 3: Open-loop spatial multiplexing

Transmission Mode 4: Closed-loop spatial multiplexing

Transmission Mode 5: Multi-user MIMO

Transmission Mode 6: Closed-loop Rank=1 precoding

Transmission Mode 7: Single-antenna port; port 5

Transmission Mode 8: dual-stream transmission, namely double-streambeamforming

Transmission Mode 9: Up to 8 layer transmission

Transmission Mode 10: up to 8 layer transmission which supports the COMPfunction.

After experiencing several versions such as R8/9/10, the Long TermEvolution (referred to as LTE) system gradually and accurately studiedthe R11 technology. At present, some R8 products began to graduallybecome commercial, the R9 and the R10 are to be further product planned.

DETAILED DESCRIPTION

As required, detailed embodiments are disclosed herein. However, it isto be understood that the disclosed embodiments are merely exemplary andthat various alternative forms may be employed. The figures are notnecessarily to scale. Some features may be exaggerated or minimized toshow details of particular components. Therefore, specific structuraland functional details disclosed herein are not to be interpreted aslimiting, but merely as a representative basis for teaching one skilledin the art.

Hereinafter, in conjunction with the accompanying drawings, theembodiments of the present document will be described in detail.

Embodiment One

The present embodiment provides a modulation processing method, appliedto an evolved NodeB (eNodeB), and including that:

an evolved NodeB (eNodeB) transmits a high-layer configuration signalingto a user equipment (UE), herein the high-layer configuration signalingis used to indicate whether to support a high-order Quadrature AmplitudeModulation (QAM) modulation scheme, and the high-order QAM modulationscheme is a modulation scheme of M QAM, herein M is a number greaterthan 64.

In this specification, the high-order QAM is also called M QAM, herein Mis a positive integer greater than 64 and is a power of 2.

In the embodiment one, M=256, and M QAM is the 256QAM.

Alternatively, the high-layer configuration signaling may be a newlyadded high-layer configuration signaling or an existing high-layerconfiguration signaling, such as an existing high-layer configurationsignaling which is used to indicate the transmission mode;

when the high-layer configuration signaling is new added, it is topredefine one or more transmission modes support transmitting thehigh-layer configuration signaling, while other modes do not supporttransmitting the high-layer configuration signaling, the eNodeB onlytransmits the high-layer configuration signaling when the transmissionmode supports transmitting the high-layer configuration signaling.

Understandably, when using an existing high-layer configurationsignaling, it is equivalent to use an implicit mode to indicate whetherto support the high-order QAM modulation scheme. In order to achieve thepurpose of implicit indication, both the high-layer configurationsignaling sender and recipient, that is, both the eNodeB and the UE,predefines the corresponding a relationship between the explicitindication content (such as the transmission mode) and the implicitindication content (refer to whether to support the high-order QAMmodulation scheme).

Alternatively, the high-layer configuration signaling which is used toindicate the transmission mode is used to achieve implicitly indicatingwhether to support the high-order QAM modulation scheme; for example,the eNodeB and the UE predefine one or more modes to support the MQAM,while other transmission modes do not support the MQAM;

Alternatively, the above-mentioned transmission modes which support theMQAM may be transmission mode 9, transmission mode 10, a newly definedtransmission mode, or, all transmission modes, or only one or morespecific transmission modes are newly defined;

Alternatively, M may also be 128, 256 or 1024.

The method of the present embodiment ensures to support or not supportusing the 256QAM with the semi-static switching, ensures to use the256QAM in reasonable environments, for example, the 256QAM can only beused in the small-cell environment.

Alternatively, the predefined information is at least one of thefollowing: a search space, a downlink control information format, aCyclic Redundancy Check (CRC) scrambling mode of downlink controlinformation.

Alternatively, the predefined information is a search space, andpredefines that: when the high-layer configuration signaling indicatessupporting the high-order QAM modulation scheme and it is in a publicsearch space, the modulation and coding scheme field (I_(MCS)) isdetermined based on the first modulation and transport block size (TBS)index table which does not support the high-order QAM modulation scheme,when the high-layer configuration signaling indicates supporting thehigh-order QAM modulation scheme and it is in the UE-specific searchspace, the modulation and coding scheme field (I_(MCS)) is determinedbased on the second modulation and transport block size (TBS) indextable which supports the high-order QAM modulation scheme;

Alternatively, the predefined information may also be the downlinkcontrol information format and predefines that: when the high-layerconfiguration signaling indicates supporting the high-order QAMmodulation scheme and the downlink control information format is aformat predefined as supporting the high-order QAM modulation scheme,then the modulation and coding scheme field (I_(MCS)) is determinedbased on the second modulation and transport block size (TBS) indextable which supports the high-order QAM modulation scheme, when thehigh-layer configuration signaling indicates not supporting thehigh-order QAM modulation scheme or the downlink control informationformat is a format predefined as not supporting the high-order QAMmodulation scheme, the modulation and coding scheme field (I_(MCS)) isdetermined based on the first modulation and transport block size (TBS)index table which does not support the high-order QAM modulation scheme.

For another example: it is to predefine that all downlink controlinformation formats corresponding to the transmission modes whichsupport the QAM modulation scheme support the high-order QAM modulationscheme, or only one of all the downlink control information formatscorresponding to the transmission modes which support the QAM modulationscheme supports the high-order QAM modulation scheme.

In step 102: the eNodeB receives channel state information of the UE,and the channel state information at least includes the channel qualityindication (CQI) information, when the high-layer configurationsignaling indicates not supporting the high-order QAM modulation scheme,the CQI information is obtained based on the first CQI table which doesnot support the high-order QAM modulation scheme, when the high-layerconfiguration signaling indicates supporting the high-order QAMmodulation scheme, the CQI information is obtained based on the secondCQI table which supports the high-order QAM modulation scheme.

In step 103: the eNodeB transmits a downlink control signaling to theUE, and the downlink control signaling at least includes a modulationand coding scheme field (I_(MCS)), when the high-layer configurationsignaling indicates not supporting the high-order QAM modulation scheme,then the modulation and coding scheme field (I_(MCS) is determined basedon the first modulation and transport block size (TBS) index table whichdoes not support the high-order QAM modulation scheme; when thehigh-layer configuration signaling indicates supporting the high-orderQAM modulation scheme, the modulation and coding scheme field (I_(MCS))is determined based on the second modulation and TBS index table whichsupports the high-order QAM modulation scheme.
